Add optional cfg_pre_init, cfg_post_init, and cfg_deinit callbacks
to handle SoC-specific configuration methods. While RZ/G3S uses the Linux
reset framework with dedicated reset lines, other SoC variants like RZ/G3E
control configuration resets through PCIe AXI registers.

As Linux reset bulk API gracefully handles optional NULL reset lines
(num_cfg_resets = 0 for RZ/G3E), the driver continues to use the standard
reset framework when reset lines are available, while custom callbacks
are only invoked when provided.

This provides a balanced pattern where:
- RZ/G3S: Uses callbacks that fall back to the
   reset framework

Nit: This fits on the previous line.

- RZ/G3E: Sets num_cfg_resets=0, provides
   cfg_pre_init/cfg_post_init/cfg_deinit

Add cfg_pre_init, cfg_post_init, and cfg_deinit callbacks to support
custom configuration mechanism in preparation to RZ/G3E PCIe support.
